If you take the FBD of CH, you will have pin reactions at C, D, E, H (with 2 unknowns at C and H, pin connections, and one unknown at D, E, pin connections but 2 forces members, so you know the direction of the forces). It makes 6 unknowns, that you can't solve with 3 equations.
Very helpful video, thank you for the clear explaination!
is there anyway to derive the right angle that pin f makes with h and e, because in the actual question its not given
is it possible to derive the right triangle between e, h and f. because in the actual problem its not given
Thank you
You're welcome
is it possible to take a FBD of CH without including the shovel part (FG)

@@fannysilvestri Yep, I realized after trying it! Thank you so much, your video was very helpful.
This is good but you complicated it. For AD, you shouldn't have separated it into compoents.
stop confusiing us
Thanks 🙏
